Solar-Electric Cars Crush Biofuels In Efficiency

run on electricity from switchgrass.
Internal combustion vehicles (ICVs) run on switchgrass biofuel.
Battery-electric vehicles run on electricity from corn.
Internal combustion vehicles run on corn-based biofuel.

The analysis considered land-use, greenhouse gas emissions, fossil fuel use, and took into account the production and use life cycles of both the fuels themselves and the vehicles they power.

In terms of land-use, solar significantly out-performed all other options. It performed modestly better than switchgrass in terms of greenhouse gas emissions, and significantly better than corn-based biofuel. Solar was actually equal or slightly worse than switchgrass when it came to fossil fuel requirements over the totality of the life cycle, but it still out-performed corn-based internal combustion. (And, of course, gasoline.)

So all things considered, a pretty clear win for solar-powered electric battery vehicles:
